Learning Objectives
Understand the acid-base theories of Arrhenius, Bronsted-Lowry, and Lewis
Identify strong acids and bases and calculate their pH’s
Calculate the pH of a weak acid or base
Calculate the concentration of a strong or weak acid or base from its pH
Calculate the pH and ion concentrations in a polyprotic acid
Predict the pH of a salt from its formula and then calculate the pH of the salt
Identify the components of a buffer and perform calculations involving the preparation of a buffer and the addition of strong acid or strong base to a buffer
Perform calculations involving strong acid-strong base titrations as well as weak acid-strong base and weak base-strong acid calculations
Be familiar with titration curves and selection of an acid-base indicator
Write balanced equations for the dissociation of a salt and its corresponding solubility product expression
Predict the relative solubilities of salts which dissolve to give the same number of ions from their Ksp values
Calculate the Ksp value from the solubility of a salt and also calculate the solubility of the salt in units of mol/L or g/L from the given Ksp value
